Don't you need a HTTP_setCCSIDs in your code?
Example:
Soap =
'<?xml version="1.0" encoding="UTF-8"?>+
<soapenv:Envelope +
// stuff goes here
</soapenv:Envelope>';
HTTP_setCCSIDs(1208: 0); // CCSID 1208 = UTF-8

Well, I gotta say that I'm really a novice at this and although I read over
your response several times and tried several other variations, I'm still
not have any luck whatsoever. This is my first foray into working with web
services from an RPG and as luck would have it, I've come across this
problem with the straight bracket [] characters.
I've tried literally hundreds of different variations of encodings, and
parameters and keep failing.
So I thought I might forward you my source code and see if you could help
define how I would code this RPG as UCS2 and then convert to UTF-8 before
using HTTPAPI.
